Final answer:
Roald Dahl uses dialogue between Timber and Harry in 'Poison' to convey Harry's shift from confidence to anxiety, maximizing dramatic tension and adding to the story's atmosphere.
Step-by-step explanation:
In Roald Dahl's story Poison, he employs dialogue between the characters Timber and Harry to effectively convey Harry's state of mind. Dahl uses dialogue to progress the plot, elevate tension, and define conflict, which in turn reveals the psychological states of the characters. For example, as the story progresses, Harry's speech patterns change from confidence to heightened anxiety and fear.
Through their conversation, Dahl manipulates the tone and pace, using short, clipped sentences or rushed dialogue to express urgency or panic. Elsewhere, longer pauses, indicated by ellipses or descriptions of silence, can signify dread or introspection. These techniques in writing dialogue add depth to Harry's character while also increasing the story's dramatic tension.
Figurative language and descriptive imagery are also used by Dahl, similes and metaphors providing an immersive experience for the reader. The tone of the story is further influenced by the word choices and structures that Dahl employs, these often serving to underscore the theme of the story or the emotional journey of the characters.
